#2 is definitely Actaea rubra.

It rained the previous day, but beautiful and sunny the day they were taken. I was on a long hike with a back pack, so I didn’t spend too much time on any plant.

#3 is indeed Amorpha canescens. Native Americans used leaves for tea and smoking.

Number 1 is Asclepias exaltata, Poke Milkweed

#1, the Asclepias exaltata as Jay IDs, is interesting. Never seen it.

Thank you everyone for helping me learn a bit more about what's growing on the woodland floor. My vision is normally focused on the overstory. :)

Now you're looking downwards is that poison ivy next to the Milkweed? (I don't mean the Virginia Creeper).

floral, I think that might be "hog peanut" (Amphicarpa bracteata)

Quite possibly. The petioles do look a bit off for pi. I’ve never seen either species irl.

It's a bit blurry to tell, but the tiny plant in the bottom right corner looks suspiciously like it might have three mitten-shaped leaves. The stuff mixed in with the creeper doesn't say poison ivy to me.
